Jeter & Mattingly Couldn't Fix Chisholm

Two of the most iconic Yankees in history tried to get Jazz Chisholm Jr. on track when he was a Marlin — and both came up empty. Bob Klapisch reported on October 15 at NJ.com that Derek Jeter, then the Marlins‘ owner, and manager Don Mattingly held multiple meetings with Chisholm, urging him to get his head straight. The uncomfortable part: the Yankees already knew all of this when they acquired him on July 27, 2024. Now Chisholm enters free agency carrying a .711 OPS and a clubhouse file that’s very much public.

The Revelation: Jeter Went to Him. Mattingly Went to Him. Neither Got Through.

The column, written by Randy Miller and Bob Klapisch for NJ.com, was primarily about the Yankees’ managerial future — but it contained an anecdote that took on a life of its own. Klapisch described how neither the franchise owner nor the field manager could change Chisholm’s attitude during his time in Miami. These weren’t casual hallway chats. They were repeated, deliberate meetings with two men who understand big-league clubhouses from the inside.

There’s earlier context that matters. In 2022, Mattingly had to call a team meeting over a conflict between Chisholm and then-captain Miguel Rojas — a dispute that escalated to the point where Rojas destroyed Chisholm’s custom cleats. That incident came before the private meetings Klapisch describes. This isn’t an isolated moment; it’s a pattern that two heavyweight figures tried to interrupt and couldn’t.

The Yankees Knew — and Made the Trade Anyway

The most uncomfortable part of Klapisch’s report isn’t that Chisholm had attitude issues in Miami. It’s that New York was fully aware and proceeded regardless. According to the same piece, the Yankees «knew all of this when they made the trade.»

There’s a wrinkle that complicates the «front office negligence» narrative: Jeter himself reportedly advised the Yankees to acquire Chisholm in 2024. Both facts coexist. The bet just didn’t pay off in 2026.

Chisholm hit .231 with a .711 OPS over 137 games — a sharp drop from his 2025 campaign (.242/.332/.481, 31 HR, .813 OPS), when he won a Silver Slugger and made his second All-Star team. Manager Aaron Boone left him out of the starting lineup in two postseason games, including the one that ended the Yankees’ season. The Yankee Stadium crowd booed him.

His wRC+ fell from 125 in 2025 — meaning 25% better than the average MLB hitter — to 98 in 2026, two points below league average. That’s not a minor slump. That’s the difference between an All-Star and a replaceable player.

Free Agency With a File: Who’s Actually Signing This?

In the spring of 2026, Chisholm told Randy Miller he’d be looking for roughly $35 million per year over 8 or 9 seasons if the Yankees offered a long-term deal. With the 2026 numbers on the table and the Klapisch report making the rounds, that figure looks very different now.

Insiders Chris Kirschner of The Athletic and Kerry Miller of Bleacher Report had already flagged long-term risk for interested teams. And there’s one detail that’s hard to ignore: Don Mattingly — one of the men who tried and failed to reach Chisholm in Miami — is now managing the Philadelphia Phillies. Chisholm publicly praised the Phillies before the end of the season. The irony writes itself.

Any interested team faces a two-sided problem. Chisholm’s contact numbers in 2026 rank in the 13th percentile in whiff rate and 9th percentile in strikeout rate — among the worst in all of MLB — with a 29.5% strikeout rate, the second-highest of his career. He still has elite speed (75th percentile in sprint speed) and real power when he makes contact (90.4 mph average exit velocity, 73rd percentile). But making contact became the problem in 2026 — and that’s before you add the clubhouse chapter.
